DESCRIPTION:
Under heavy load, a SHM application running on a multi-CPU host experiences heavy contention for the bulletin board
lock. tmadmin bbi shows
Average queue length: 10.06
When truss -u "libtux::*" -p <pid> is used to trace the behavior of one of the heavily-loaded Tux
application servers, it shows that the process is updating its service cache before every tpcall() invocation. These
cache updates appear to be unnecessary.
CONFIGURATION:
Tuxedo 8.0
